BOX-NAILING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 230,230, dated July 20, 1880.

Application led April 5, 1380.

To all whom it may concern:

Be it known that I,WILLIAM H. BROCK, of Corona, in the county-of Queens and State of New York, have invented an Improvement in Box-Nailing Machinery, of which the following is a specification.

Before my invention numerous devices had been made for aiding in the manufacture of boxes. ln some instances the parts of the box have been held firmly in their proper relative positions while the nails have been driven by hand. In other instances the nails have been supplied automatically and driven into the wood by a plunger or punch.

My invention is available in the manufacture of boxes where one particular size of box is required. I employa form that corresponds .t0 the internal measurements of the box. The

sides ofthe box are supplied to the respective sides of this form. `Springclaws act to carry the sides of the box down with the form, and the nails are driven automatically. The form then rises, and the additions ofthe side pieces for the nextbox cause the box that has been nailed to be held while the form draws partially out ot' the nailed box. The sides of the second box are nailed together as the form is carried down, and the sides of the third box hold those previously nailed, and as the form is drawn off the first box drops upon a belt and is carried to an elevating-shoe, Where an attendant lifts the box and applies the bottom, and nails the same upon the sides, either by automatic mechanism or by hand.

In the drawings, Figure l is a vertical section transversely of the machine. Fig. 2 is a longitudinal section, and Fig. 3 is a crosssection at the line a:

The bed a stands on suitable legs a', and upon it are the columns b, that support the form-carrier c and hoppers or chutes d d e e;

The standards c support the driving-shaft f, and suitable power is applied to revolve the same.

j" is the driving-pulley, and 4 is a clutch for starting and stopping the machine.

The form g is of the same size as the inside measurement ot' the box, and it slides freely in, but it is guided vertically by the form-carrier c, and there is a counter-weight, lq,within the hollow form, and cords or chains 2 2 pass (Model.)

from the counter-weight over pulleys on the shaft f, and connect to the cross-bar 3, so that the form can be moved up or down with but little power.

In order to draw the form up I make use of a gear-wheel, h, upon the shaft fand a rack, lc, that is hinged at its lower end to the upper end of the form, and such rack has a handle or lever, k, by means of which it is brought into gear with the teeth on the wheel lL. The revolution of the shaftfturns the wheel, and its teeth act upon the rack and raise the form to the proper height, after which the rack is disconnected from the teeth of the barrel. This is done after each box has been nailed, so as to draw the form out of the box, as before mentioned.

The wood is sawed up into the proper widths and lengths, and supplied in a vertical position into the hoppers, those marked d receiving the side pieces and those marked e the end pieces, and there is the necessary distance between the innerends of the hoppers or chutes and the forni for the wood to pass down. v

There are spring dogs or claws 6 in the form that spring out over the upper edges of the wood, and they carry the four pieces compos ing the sides and ends of the box down with the form as the form is moved down, and the nails are driven into the wood to fasten the sides and ends together.

VrIhe means for applying the nails are of any usual or desired character. There are four of these at the angles of the box. Each has a hopper, l, a separator, 8, to let one nail at a time pass down from the hopper, and a punch, g, to drive the nail. Y

Each punch is operated by a crank, m, that is at the end of a short shaft supported in the arms n, that project from a cross-bar above the columns b, and from cranks 19 at the ends of the short shafts there are connecting-rods l0 to cranks 1l atv the ends of the driving-shaft f, so that all the four nailing appliances are operated simultaneously.

It will be apparent that the punches are operated to drive the nails once for each revolution of the shaftf, and as the punches are being drawn back to take another nail I operate the mechanism. that carries down the forni and the four sides of the box so as to bring IOO the cross-bar 3 of the form.

5o on.

them into position for theinsertion ofthe next nails. I eect this by the action of an eccentric, 12, on the shaftj", that moves up and down a ratchet-bar, 0, the teeth of which take into rIhis eccentric forces the ratchet-bar o down as the nailpunchcs draw back, and moves the form and box sides down. The ratchet-teeth correspond to the distance between one nail and the next.

Io The ratchet-bar 0 has a lever-handle, 0', by

which the attendant brings it into action when the nailing is progressing, and when the attendant releases his hold upon the lever the rack-bar swings out of action by the weight of the lever.

If desired, two levers, rack-bars, and eccentrics may be used, as shown, to act simultaneously in forcing down the form at both sides of the center thereof` to insure parallelism of zo movement; ortheraek-bars may be made with teeth of dii'erent sizes, so as to vary the distances between the nails, as required.

From the foregoing it will be understood that the sides ofthe box are firmly nailed together on the form. and that the friction be- 3o such box down while the form is raised, be-

cause the upper edges ot' such four pieces are beneath the lower edges of the fornrcarrier c, and thereby the form partially draws out from the box, leaving the box projecting below it. When the form is drawn n i the scc- 3S ond time it draws entirely out ot' the box, and said box drops upon the belt r. The opening in the bed a allows the box to pass freely through the same, and the belt or carrier r,

4o.traveling in the direction indicated by the arrow, carries the box to the shoe t, thatis made with stops 15, that arrest the cndwisc move ment ofthe box, and said shoe is guided by the vertical slide-bars a, aml is lifted by the treadle fu, so that when the tour sides ot the box have been received into the shoe an attendantlii'ts the shoe, carrying the box up into an opening in the bed a, at which place the bottom piece of the box is applied and nailed This nailing may be done by hand; but I have shown the sets of punches w and hop-` pers 2l for the nails, said punches '1v being operated by the crank-arms 22, rocloshaft 23, crank 28, and connecting-rod 24 to one of the cranks 19. After the bottom has been nailed upon the box the treadle is released, the box lowered and removed.

1 claim as my invention- 1. In a box-nailing machine, the combination, with the form, of four hoppers or chutes to supply the four sides of the box, and naildriving mechanism applied to drive the nails simultaneously at the four angles, substantially as set forth.

2. Ina box-nailing machine, the combination, with the form, ot' the form-carrier, the counter-balance within the hollow form, four hoppers or chutes, dogs for carrying' down the wood, nailing mechanism, and a toothed rack and actuating-eccentric for moving the form, substantially as set forth.

8. In a box-nailing machine, the combination, with the lorm, of the driving-shaftf, eccentric !2. toothed rack-bar o. and lever o', for moving;` the same, substantially as set forth.

4. ln a boxalailing machine, the combination, with the vertically-sliding' form, ofthe rack lc, lever 76, and gearwheel IL, substantially as set forth, to raise up the form.

5. In a box-nailing;` machine, the combination, with four nail-driving` appliances, of the connecting-rods 1l), cranks l1 19 m, and driving-shat'tf, for actuating the drivers simultaneously, as set forth. I

6. In a box-nailing machine, the combination, with the form and mechanism for nailin gr the four sides together, of a belt or carrier for receiving' the partially-formed box, a shoe and lever forraising; the same, and a bed with a guide-opening to steady the parts while the bottom is applied and nailed 011, as set forth.

7. The combination, in a box-.nailing ma chine, otl a form around which the four pieces of wood are supported while being nailed, four automatic nail-driving devices at the respective corners, and mechanism for actuating the nail-drivers, substantially as specified.
